At low tide the Shark River shows its bottom — stone, shell and channel mud — and the early sun comes up the water into Belmar from the east. River Stone Landscaping & Hardscaping LLC starts its lawn days in that hour, cutting and trimming while the dew is still down and the town is quiet. Edging follows: one clean line where turf meets walk, held straight the length of the block. Cleanups in spring and autumn clear the beds and borders so a yard has room to breathe at both ends of the year. On lots measured in feet rather than acres, the finish is the entire point.
